Personally, from a testing standpoint I really like the ParosProxy but the last time I checked it does not have very good fuzzing capabilities. Using some of the other free tools (like BurpSuite) fixes that but as I also have other issues to monitor and test being able to automate some of these tasks and increase my reporting output might actually be worth spending some money.

Yes, so far it appears that Watchfire (AppScan) and SPI Dynamics (WebInspect) are the big players in this field with their inclusion of development modules and review (whitebox testing). But I am hoping to determine if anybody has any insight to whether or not the other products stand up to them in the field of automated assessment and pentesting (blackbox) and reporting output.
